BONASIL A+ Crystal Vision is a transparent laboratory vinyl polysiloxane (VPS) impression material with medium viscosity. Its novel formulation produces highly transparent matrices through which the lab technician can polymerize light-curing composites and detect the accurate waxing placement and the reproduction of composite. Indications • Transparent matrix for creating masks for the moulding of light-curing resins Characteristics-Advantages • Outstanding transparency • Exceptional dimensional stability • High final hardness • Highly thixotropic • Ideal consistency • Very high tear strength • Void free • Composites free from oxygen inhibition layer
